Tesla developed a proprietary linear actuator built around an inverted planetary roller screw as a key element of the Optimus Gen 2 design. The inverted topology delivers high axial force in a very compact package, and the multi-roller load path that replaces ball-screw balls dramatically improves shock-load capability.
The robot uses 14 of these linear actuators — primarily in the legs — complemented by rotary actuators in the remaining joints. According to Tesla's presentation, the roller screw delivers around 3× the sustained load capacity of a comparable ball screw and is resistant to brinelling, which is critical during dynamic humanoid walking.
Linear Actuator · serves as: Joint Actuation, Locomotion Drive, Motion Generation, Torque Transmission. · compatible with: Humanoid, Biped.
Which group Tesla Optimus Roller Screw Linear Actuator belongs to and how it is built
A linear actuator is a component that converts electrical, pneumatic, or hydraulic energy into linear motion. In robotics, it is used in extension, lifting, translation, positioning, and displacement-control mechanisms. Linear actuators are employed in manipulators, mobile robots, industrial systems, and mechatronic applications that require controlled rectilinear movement.
